COOKING-STOVE.

T e Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern.-

Be it known that I, JAMES H. MCGONXELL, of Beaver Falls, in the countyof Beaver, and State of Pennsylvania, have invented a new and usefulImprovement-in Stoves; and I do hereby declare that the following is afull and exact description thereof, referencebeing had to theaccompanying drawing and to the letters of reference marked thereon.

The nature of my invent-ion consists in so constructing a stove that itsfire-back shall have an airchamber in the rear of it, communicating witha flue which passes over the top plate of the oven of the stove.

My invention also consists inproviding the fines of the stove with adamper or valve, so constructed that, when it has closed the most directopening to the stove-pipe or chimney, there shall be a communicationbetween the air-chamber in the rear of the fireback and the stove-pipeorchimney.

To enable others skilled in the art to makeand use my invention, I willproceed to describe more fully its construction and operation.

In the accompanying drawing my specification- Figure 1 is a vertical andlongitudinal section of an ordinary stove provided with my improvement.

Figure 2 is a transverse section of the same.

Figure 3 is a face view of the damper or valve of the stove.

The stove represented in the accompanying drawing is of ordinaryconstruction.

A represents its fire-back, in the rear of which is an air-chan'lber, B,which communicates with the flue O, which communicates with the pipe orflue S.

which forms part of The fine O is arranged on the top plate c'of thepivoted at the back end of the flue Q, between the flue-plates a.

"As the construction and arrangement of my improvement, with relationto'the ordinary cookingstove, will be readily understood from theforegoing description and by reference to the accompanying- .drawing, Iwill therefore proceed to describe its operation, whichis as followsiThe air passes, at openings in the sides of the stove, into the chamberB, where it becomes heated it then passes into and through the flue G,into the stove-pipe flue S, and out through the stove-pipe or chimney;\Vhen the damper on is in the position turned up, as shown in figs. land 2, then the" communication between the fines O and S is kept open bymeans of the opening a in the damperm. When the damper is up the heatand smoke will pass back and down the fiues land 1, and through thefines l to a very great degree, the fire-plate from burning out, andoverheating the front and the central portion of the top of .the oven,equalizing the heat in all parts of it.

Having thus described the nature, construction,

and opera-tion of my improvement,

What I claim as of my invention is' .l. -Providing the air-chamber, backof the fire-plat of a cooking-stove, with a flue, which passes over thetop'plate of the oven, as herein described, and for thc purpose setforth.

2. Combining with the above flue and air-chamber the damper an, arrangedand operating substantially as herein described, and for the purpose setforth.
